Interference gas removal filter (CF-8392) replacement
procedure
The interference gas removal filter (CF-8392) is installed to the detector to remove interference gases that
damage sensors for silicone, sulfides, etc.
Continuing to use the detector may cause the filter to be contaminated or clogged. Replace the filter when
it has absorbed water or oil, etc. or has a lower flow rate due to clogging, or when the sensor sensitivity
deteriorates significantly.
Install the filter by sliding the grooves on its sides to the guide of the case.
Sensor replacement
The sensor comes with a 1-year warranty. It has a typical life of 2-3 years, depending on the operating
environment. The sensor life has expired if, for example, there is no response during a calibration. Contact
RKI for sensor replacement.
Battery replacement
For battery replacement, see "How to replace the batteries" on page 13.
